I guess I should be more specific. The problems with Air China are not their SOPs, it is a lack of adherence to them. This is second hand, I do not work for Air China and never have, but I do have it on pretty good account that the standard of adherence to the procedures is quite diverse. The other problem at Air China (and this is certainly not peculiar to them and the same could be said about CX) is the single pilot fast jet mentality that persists with the ex-mil pilots, who also tend to be in the left hand seat. Sure, the SOPs are fine, and so they should be as they are generic, but whether or not people actually follow them (and understand them) is another matter.
